Answer: 1. A
2. C
3. B
Step-by-step explanation:
1. This sentence is future tense because of key words like 'unless'. hence the correct verb for the sentence is 'will not'. 'won't' also works, but 'won't not' doesn't make sense.
2. When referring to a plural noun, 'their friends', the correct verb is 'have' since it refers to something plural. The other verb options are for singular nouns.
3. When referring to a plural noun, 'they', the correct verb is 'were' since it refers to something plural. 'they living' doesn't make sense.
